Call Control is a prepaid application that can be used together with
OpenSIPS call_control module and CDRTool rating engine to limit the
duration of SIP sessions based on a prepaid balance. It can also be used
to limit the duration of any session to a predefined maximum value
without debiting a balance.

SIP SIMPLE client is a Python software library built on top of PJSIP
that together with middleware allows for easy development of
Client/Server and Peer-to-Peer Internet communications end-points based
on SIP SIMPLE protocols for voice, video, presence, instant messaging
(IM) and file transfer capabilities. For more information go to
http://SipSimpleClient.org

Version 1.0 of OpenXCAP server is now available. It contains many bug
fixes and additions for important features like XML partial
manipulation, xcap-caps, xcap-diff and RLS services that were not
available at the initial release last year.

AG Projects participates to the 23-rd edition of
SIPit, a week-long
event where people bring their SIP implementations to ensure they work
together. AG Projects will participate with its new releases of OpenXCAP
and MSRPRelay servers and a SIP SIMPLE test client.

Euroweb Romania upgraded its SIP voice network (Eurovoice) to a
distributed, multiple-site architecture located in three cities,
Bucharest, Timisoara and Iasi. By deploying this self-organizing
architecture is now possible to increase the availability of the
provided voice services, by eliminating downtimes related to
communications' packet-loss or Internet connectivity failures. The voice
traffic can now be automatically rerouted between any of the mentioned
location, in a short notice and without major engineering works which
were necessary prior to this upgrade.

SIP2SIP.info provides free SIP accounts that allows communication using
audio and video over the Internet using the SIP protocol. The account is
Presence/IM enabled with support for relevant SIP SIMPLE standards for
MSRP relay extension, Presence Agent, XCAP and RLS services.

The service is provided in multiple data centers using AG Projects' SIP
Thor solution.

AG Projects launches MSRPRelay, an Open Source implementation of IETF
standard RFC 4976. MSRP relay is an extension to the MSRP protocol (RFC
4975). Its main role is to help NAT traversal of Interactive Messaging
and file transfer sessions for SIP/MSRP endpoints located behind NAT.

P2PSIP working group will be born at ETF68 (Prague). This new protocol
will enable a new range of prosumer orineted services that will be made
possible by moving inteligence from the network into the end user
devices.
